I have (happily) got to the point of running three sessions a week, from 6-11k (depending on how I feel!). I have never run on a treadmill before, but as I live in a snowy part of the world I have decided I need to buy one in order to get through the winter. I will put it in the garage or cellar (don't have loads of free space). I am aiming to buy from eBay as I'm sure there are bargains to be had there.

Does anyone have any recommendations on what I should aim for? I certainly don't have an unlimited budget, but don't want to buy one thats too "Mickey Mouse" for my running, if you get what I mean. I'm not a pro, but don't want to buy something that won't allow me to run the way I run.
